Application filed January,11,-1'926.H'Scria1 No. 80,5573. v

This invention relates fto improvements revaporizers, more particularly adapted for use with internal combustionengines.

ln the use of internal combustion engines, :it has been foundl that the gasoline which is drawn through the carburetor does not thoroughly mix lwith the airjand revaporize,.with

the result that liquid fuelis drawn, through the intake manifold, into the cylinders of the engine, resulting in loss of eiliciency, waste of fuel and actual damage to thevengine due to diluting the lubricating oil, eX- cessive carbon formation and causing the engine to overheat. v l

It is one of the objects of thepresent invention to overcome the before mentioned objectionable features, and providea revai poiizer which will thoroughly vaporizeithe gasoline before it enters the intake manifold.

vide a revaporizer which willv collect and trap thatportion of thefuel which passes through the carburetor in liquidform and properly mix the liquid with sulhcientair to vaporize it before it reaches the cylinders of the engine.

A further olnectV of the invention is to provide a revaporizer which 1s automatically y operated and regulated by the suction, and ""i variationin suction, of the engine in draw-r mg the fuel into the cylinders of theengme.l

A further object of the invention is to provide a revaporizer carburetor whichwill indicate to the user whether or not ythe maink carburetor is properly adjusted to produce the most efhcient results. i i

A further object of the invention. is to provide a. revaporizer carburetor inwhich the fuel passing through the carburetor is visible at all times. f c

A further object of the invention isto provide a revaporizer carburetor Vwhich automatically provides a rich mixture'of fuel for starting the engine. l l

further object .of the invention is.` to provide a revaporizer carburetor which is of simple construction, is strong and dura vble, and is well adapted for the purposesdescribed lilith the above and other objects inview,` the invention' consists of the improved revaporizer carburetor, and its partsand combinations set forth in the claims, and all equivalents thereof.- 1 In the accompanying drawing in which A further obj ect of the invention is to pro.

the` same l reference characters indicate f the samev parts in all f theviewsr;y i f f ,Fig 1 is yvertical transverse sectional View Y of Y the improved reya'porizer carbure- 4F 2 isajtop- View thereof; and vFig. 3 isa sidefview of' the ,revaporizeii carburetor shown Iinterposed ybetween portionslof a carburetor andthe intake mani,` foldofan internal combustion engine, parts being broken away andv other partsbeing shown `in section. i l v Referring to the drawing, the numeral 5 indicates a portion of the intake manifold of an internal combustion engine, and 6 a portion'rof a carburetor for vaporizingl a fluid fuel .and supplying the gaseous vapor to the cylinders/of the engine through said intake manifold. Inv ordinary use, the carburetor is connected directly to the manifold, but lin .l the present use they are spacedapart a slight distance to receive the revaporizer carburetorr 7 interposed therebetween. Said revaporizer carburetor isy provided iwith an attaching portion or. flange 8, which lextends betweenthe flanges or ends of the carburetor and the intake manifold, respectively, and isf flange 8 vfrom the opening 10 to the inner, sideof the-cap 1l and a suction tubel extends'through said opening or duct 14 and terminates at its lower end at a point about midway of the height of the receptacle. The upper end l5 of the suction tube terminates about ymedial'ly7 of the diameter of the opening 10 and is of angular or oblique formationwith relation to the length of the tubev` with the ,oblique portion extending toward the bore of the intake manifold 5. The duct 214 is of greatertransverse length than thediameter of the tube, and to deflect the heavier-:vapor and unvaporized fuel downwardly through the opening 14, a deflector plate 16 is positioned transversely of the duct l()V on the intake manifold side of the lll() tube 15, and its upper edge portion 16 is angled toward the carburetor. This deflector 16 intercepts the liquid and heavier vaporiZed fluid, and directs it downwardly through the duct 14 and into the transparent receptacle 13 while the lighter and properly vaporized combustible fuel flows above and around the upper end portion of the suction tube 15 to the intake manifold. An inverted cup-shaped or tubular extension member 17 surrounds and is connected to the portion of the tube 15 within the receptacle at a point above the lower end of the tube. The tubular member 17 is of greaterdiameter than the tube 15 and its lower end terminates a short distance above the bottom portion of the receptacle so that if any liquid fuel should be drawn into the extension tube, it can work up the inner sides of the tube, but will be prevented from entering the lower end of the tube'15, due to the fact that at a point approximately horizontally opposite the lower end of the tube 15, all upward suction through said tube 15, upon the content of the tubular member 17 ceases and at such point the upward progress of any liquid working up the inner sides of said tubular member must stop. An additional deterrent is the slower suction speed in the tubular member 17 due to its diameter being greater than that of the tube 15, through which suction of the engine is communicated to the receptaclel.

An air intake tube 18 extending through the cap 11 and downwardly into -the receptacle is formed with a lower curved end portion 18l which is directed in a line tangentially to the axis of the receptacle to impart a swirling or circular motion to the fluids within the receptacle, when the receptacle is subjected to suction from the intake. manjfold through the suction tube 15. The upper end 19 of the air tube 18 terminates adjacent the attaching ange 8. n

The numeral 20 indicates the ordinary butterfly val-ve Vfor controlling the carburetor.

In operation, the suction from the engine will draw the fuel from the carburetor and the lighter or properly vaporized fuel will flow over and around the upper end portion of the suction tube, while the fuel in liquid form and heavier or too rich vapor wil'l be deflected downwardly by the plate 16. Suction, increased by the obstruction in the opening` 10 of the suction tube and the defector plate, through the suction tube 1,5, will be created in the receptacle 18 to draw the vapor therefrom into the intake manifold of the engine. The suction or partial vacuum in the receptacle will cause air to rush into the receptaclethrough the tube 18, and as this air is directed ina tangential path with re'lation to the axis of' the receptacle, any liquid or vapor in the receptacle will be given a circular or swirling motion, and the heavier particles will, by centrifugal force,

be caused to flow around the outer periphery of the swirling fluid.

The suction in the tube 15 and its extension 17 will draw up the lighter or properly vaporized fuel, while the heavier fuel will continue to swirl and mix with the incoming all' through the tube 18 until it is properly mixed, and when mixed it also will be drawn into the suction tube 15 and the intake manifold and to the engine cylinders. If by chance any of the liquid fuel should be drawn into the extension tube 17, vthe swirling motion imparted to the liquid will cause to work up the inner sides ofthe extension 17, while the lower plane of the end of the tube 15, with relation to the top of the extension, will prevent the flow of the liquid into said tube 15. In stopping the operation of the engine, the vapor in the tubular portions of the intake manifold and other parts `will condense and willin addition to the liquid fuel spilled by the carburetor, flow into the receptacle, and the level will rise above the lower edge of the extension 17. In restarting the engine, the suction will at iirst draw up the unvaporized fuel which closes the lower end of the extension and form a very rich mixture for starting the engine. A further advantage resides in forming the receptacle of transparent material, as the operator can watch the flow of fuel through the receptacle, and if too much of the fuel in liquid form is deposited in the receptacle, it is a clear indication that the carburetor is set for too rich a mixture.

'From the foregoing, it -will be seen that the revaporizer is of very simple const-ruction, and can be `easily attached te an engine to more thoroughly vaporize the fuel supplied thereto.
